STAPLING-MAGHINE.

Specification of Letters Patent.

Patented Mar. 28, 1916.

Application filed April 8, 1915. Serial No. 19,891.

To all whom it may concern:

Be it known that I, HENRY WEBER, a cit zen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented certaln new and useful Improvements in Stapling-Machlnes, of which the following is a specification.

This invention relates to a stapl1ng-machine designed especially for use 1n constructing containers made of card-board or other similar material, and for fastening the closures on such containers. It may, of course, be used for other purposes 1n WlllCll comparatively thin material is to be fastened.

The invention consists substantially'in the combination and arrangement hereinafter described, illustrated in the accompanying drawings, and more particularly set forth in the appended claims. 1

In the 'drawingsFigure 1 is a fragmentary front elevation of a stapling machine embodying my invention. Fig. 2 is a top plan view of such a machine. F1g. 3 1s a fragmentary vertical sectional vlew showlng the way in which the work is presentedto the stapling head. Fig. 4 is a perspective view with parts broken away, showmg one form of container for which the present 1nvention is especially adapted.

In the drawings, the numeral 1 represents a standard or support for the machine embodying the presentinvention. The base but the supfor the support 1 is not shown, port carries at its upper end two laterally projecting arms 2 and 3, spaced one above the other. tremity a stapling head 3, of well-known construction, adapted to form staples from a continuous wire and force them into the material to be stapled. Stapling heads for this purpose are well knownin the art, and it is not necessary for the purpose of this application to show or describe the detailed construction of such a head. It is suificient to say that. themechanism contained in the stapling head is driven from a pulley wheel 4, and that the staples, after they are formed, are forcedoupwardly from the upper central portion of the extension 5 carried at the upper part of the stapling head. The wire 6, from which the staples are formed, is

carried on a spool 7 mounted on the standard 1. It should be noted that the head 3 is located in an inverted position, so that The arm 2 carries at its ex-.

the staples are forced upwardly instead of downwardly, as is the usual method of operation of stapling machines. Mounted on a pivot 8 carried on lugs 9 and 10 on the standard 1 is a work table 11. This table is free to swing in a horizontal plane upon 8 as a pivot and when in operating position is supported by a member 12 carried by the arm 2 which supports the head 3. The table is partially cut away, as at 18, to leave an open space above the portion 5 on the stapling head to permit the portion 5 to cooperate with work supported on top of the table.

Adjustably mounted on the upper surface of thetable is an angle-bar 14 which is held in position on the table by pins 15 passing through openings in the angle-bar and adapted to enter any one of a series of holes 16 in the table top. The bar 14: acts as a gage to limit the position of the work, as will be explained. Also mounted on the top of the table is a pair of stops 17 adapted to be adjustably held in position by pins 18 which enter openings 19 in the table top. The stops 18 have inwardly beveled or sloping surfaces 20 adapted to cooperate with a cylindrical container to hold it in position, as is indicated in Fig. 1. As is apparent, these stops may be adjusted to accommodate different sized cylinders. The upper arm 3 carries at its extremity a downwardly bent portion 21 on which is mounted a clench or anvil member 22 which extends forwardly from the projection 21 over the part 5 of the stapling head into position to be struck by the ends of staples that are forced upwardly by the stapling head. and thus bend over the ends of the staples and clench them in the work that has been stapled. Adjust- 23 is an L-shaped gage'24lcarrying a laterally projecting arm 25. The arm 25 is slotted as at 26, and a forwardly projecting pin 27 is mounted to slide in the slot 26. A thumb nut 28 is screwed onto the end of the pin 27 to hold the pin in adjusted position. Graduations 29 are formed on the upper surface of the arm 25 to assist in properly locating the pin 27.

In Fig. 4 is shown one form of container in connection with which the present stapling machine is used. In packaging material, such as coffee, beans, sugar, etc, in a container of this character, the cylindrical portion 30 of the container is first formed of very heavy fibrous material. The container itself may be as large as a foot and a half in diameter, and the material of which the cylinder 30 is formed will be approximately from i to in thickness. After the cylinder 30 has been formed, one of the circular rings 31 of similar material.to that from which the cylinder 30 is formed, is secured in one end of the cylinder, the edge of the ring 31 being flush with the end of the cylinder. This ring is fastened in the cylinder by placing the cylinder with the ring in position upon the work table 11 between the guides 17 and resting against these guides as shown in Fig. 1. The gage 14- is adjusted to the proper position to permit the end of the cylinder 30 to' extend the proper distance between the parts 5 and 22 to properly position the staple relative to the edges of the ring 31. The member 2a is adjusted on the bolts 23 to bring the finger 27 in position to extend slightly into the open end of the cylinder. The finger 27 is then adjusted longitudinally of the arm 25 to a position where it is spaced from the clencher 22 a distance approximately equal to the distance that it is desired to have the staples spaced from one another circumferentially about the ring 31. The machine is then operated and a staple is forced upwardly by the head 3 into and through the cylinder 30 and ring 31 and is clenched by the member 22 on the upper or inner surface of the ring 81. The cylinder is then rotated upon the table top in a counter-clockwise direction as viewed in Fig. 1 until the staple that has already been placed is brought opposite the finger 27 The machine is then operated a second time and another staple placed in position. This operation is repeated until staples have been equally'spaced about the entire periphery of the cylinder. The container is then removed from the machine and placed upon end with the ring 31 downward. A circular disk 32, of a diameter equal to that of the interior of the cylinder 30 is then placed within the cylinder and allowed to rest against the inner edge of the ring 31 that has been stapled in position. This disk 31 now forms the bottom of a cylindrical container which is as yet open at the top. The container is then filled with whatever material it is desired to place within it, a space being left at the top equal to the width of a ring 31, and the thickness of a disk 32. A second disk is then placed upon top of the material in the container and a second ring 31 placed above the disk within the end of the cylinder, and the edge of the ring and end of the cylinder brought to a position where they are flush with one another. The operator then holds the container with his fingers in posi? tion to retain the ring 31 in place, and places the filled cylinder upon the table 11 again,

but this time with the other end in position to be operated upon by the stapling mechanism. It is in stapling this last ring in position, after the container has been filled, that the present machine is particularly advantageous. Since staples are inserted from below, the entire weight of the filled container may rest upon the table 11,- and all that is necessary for the operator to do is to hold the ring 31 in place until one or two staples have been inserted, and then to ro= tate the cylinder from one position to the next after each stapling operation.

While I have shown, by way of illustra tion, the stapling machine as used in connection with a cylindrical container, it, of course, is understood that the machine may be used as well in connection with a variety of articles, such, for instance, as for stapling the bottom and cover of a rectangular container, or for stapling various articles that will readily suggest themselves to those skilled in the art, and it is distinctly understood that I do not wish to confine myself to any particular form of work upon which the machine is operated.
